A SPECIFICATION forming part of Letters Patent No. 505,371, datedSeptember 19, 1893.

Application filed June 20, 1893. Serial No. 478,263- (No model.)

rectly from the trumpets to the calender rolls;

I arrange the clearer, or rather clearers, since I use two clearerstrips or platesso that they shall effectually cover the exposed partsof the calender rolls-these clearers being placed upon the oppositelongitudinal edges of the trumpet plates, and they further are so heldas to be capable of removal and replacement, while the machine isrunning and without interfering with the operation of the other parts,giving sure protection to the slivers, and requiring almost no care orattention on the part of the operator. It is in this combination andarrangement of instrumentalities that my invention is comprised.

The nature of my improvement and the manner in which the same is or maybe carried into effect will be readily understood by reference to theaccompanying drawings in which- Figure 1 is a front elevation of so muchof a coiler drawing frame as needed for the purpose ofexp]anation-representing the application thereto of my invention in itspreferred form. Fig. 2 is a cross section of the same Fig. 3 is a sideelevation of one of the intermediate bearings of the frame.

The front and rear calender rolls are sho wn at O C; but one completeset is shown, supported in the end bearingK, and theintermediatebearings A, B. Where, as is usual, there are a number of sets, theyextend from side to side of the machine, theintermediate sets beingsupported in intermediate bearings A,B. The cans are shown at N; thecoiler tops at N -all constructed and arranged to operate in the usualmanner. i

T is the trumpet plate placed directly above and extending lengthwise ofthe calender rolls, and supported by the end bearing K and intermediatebearing AB; in it are formed the trumpets T for passage of the sliverfrom the front drawing rolls (not shown) to the calender rolls.

Against each longitudinal edge of the trumpet plate is fitted aclearerL, which rests upon the calender roll with which it is intendedto co-operate, having its curved inner face which rests upon the rollarmed or covered with cloth; each clearer overhangs and effectuallycovers the exposed portion of its roll. Each clearer extends the lengthof the trumpet plate and is supported in the bearings K and AB. For thispurpose it has on one end a pine which fits in an inclined notch 17 cutin the inner face of the portion of the bearing K by which it iscarried, and on the other end a pin or stud c which enters and fits aninclined slot (1 in the intermediate bearing A B, the notch and slotbeing inclined in such direction that as the clearer tends to dropslightly by its weight, it will be forced into closer contact with thecalender roll. For the same purpose each clearer may be provided with aweight W, hung from a weight strap M, held in a groove or slot 6 in theclearer, and passing over and down upon the inner side of the axle ofthe calender roll. The adjustment is such that the joint between thetrumpet plate and each clearer is a tight one, and that the top of theclearer at the joint is flush with the top of the trumpet plate. In thisway the outside of the clearer can be kept perfectly clean with entireease, all that is needed being to wipe or dust it off from time to timewith a brush or cotton waste. At the same time the clearer can beremoved easily whenever necessary, this being made feasible by thearrangement of the joint. All that is required forthis purpose is tolift the pin 0 out of its slot cl, after which the pin a can readily bewithdrawn from its notch b, and with the same ease and expedition theclearer can be replaced.

This improvement with such mechanical changes as will readily occur tothose skilled in the art is applicable to any and all drawing frameshaving a coiler attachment.

I desire it to be understood also that I do not limit myself to theparticular form of joint between the clearers and their supporting frameor bearings. This can be modified and changed considerably withoutdeparture from my invention.

Having now described my improvement and the best wayknown to me ofcarrying the same into effect, what I claim herein as new and of my owninvention is 1. The combination with the calender rolls and trumpetplate of clearers placed in front and rear respectively of the trumpetplate and detachably connected to their supporting frame or bearings, soas to be removable and replaceable, substantially as and for the purposehereinbefore set forth.

2. In combination with the calender rolls and trumpet plate, theclearers fitting against the front and rear edges of said plate andoverhanging the exposed portions of said rolls, and supported inbearings inclined in a direction to cause them to tend by their weightto hug or press toward their respective rolls, substantially as and forthe purposes hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.
